A -0.06 charge that moves downward is in a uniform electric field with a strengthened of 200 N/C. What is the magnitude and direction of the force on the charge
Answer:
The magnitude of the force is 12 N Upwards
Explanation:
The force on a positive charge will be in the same direction as the field, but the force on a negative charge will be in the opposite direction to the field. Thus the direction of the force is upward.
Given;
magnitude of charge, q = 0.06 C
magnitude of electric field, E = 200 N/C
The magnitude of the force is given by;
F = qE
F = 0.06 x 200 N/C
F = 12 N Upwards
Therefore, the magnitude of the force is 12 N Upwards
Answer:
A. 12N up

Answer:
1. Collision- the sudden, forceful coming together in direct contact of two bodies
2. Newton's third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction.
3. Momentum is the product of a moving object's mass and velocity. When two objects collide the total momentum before the collision is equal to the total momentum after the collision

If a planet's orbital speed is 20 km/s when it's at its average distance from the sun which is most likely orbital speed when it is nearest the sun?
Answer:25km/s
Explanation:
The planet's orbital speed is higher when the planet is nearest to the sun.
The planet's orbital speed increases when it is nearest to the sun because of the strong gravitational force of the sun. A planet's orbital speed depends on the distance from the sun. The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves.
The farther it is from the Sun, the weaker the Sun's gravitational pull on the planet so it moves slower in its orbit around the sun so we can conclude that the planet's orbital speed is higher when the planet is nearest to the sun.

Answer:The sun produces energy through nuclear fusion.
Explanation:
The sun produces energy through nuclear fusion. The sun is a large ball of hydrogen and helium undergoing constant nuclear fusion, in which atoms of hydrogen combine to form helium and release a large quantity of energy. The enormous pressure in the sun keeps the fusion running for huge amounts of time.

Read the claim about caffeine. Caffeine improves mental alertness and motor coordination. A university research study was conducted to examine how caffeine affects fine motor skills. Ten teen girls, ages 14 to 18, were given 200 mg of caffeine per day for 30 days. Thirty minutes after taking the caffeine, each subject took a timed fine motor skills test in which they fitted 20 small beads onto pegs. The graph compares each subject’s average results on the same test done 30 minutes before and after taking the caffeine. Which group would most benefit from the claim? people who sell coffee with caffeine people who sell decaffeinated tea diners that serve only drinks without caffeine manufacturers of caffeine-free bottled fruit juice

Q3. At an altitude of 6679 km above the center of the Earth, the
International Space Station can complete one orbit in 1.5 hours.
Determine the average speed of the ISS. Explain why you should
calculate speed in this case, and not velocity.
Answer:
5524.8 m/s
Explanation:
Given that,
Altitude above the surface of earth is 6679 km, the Space Station can complete one orbit in 1.5 hours. We need to find the average speed of the ISS. The average speed of its orbit is given by :
[tex]v=\sqrt{\dfrac{GM}{R}}[/tex]
R is distance from Earth
R = r + d, r is the radius of Earth
R = 6371 + 6679
R = 13050 km
So,
[tex]v=\sqrt{\dfrac{6.67\times 10^{-11}\times 5.972 \times 10^{24}}{13050\times 10^3}}\\\\v=5524.8\ m/s[/tex]
or
Hence, the average speed of ISS is 5524.8 m/s.
*it’s actually carpentry*
two basic types of scaffolds are
a. metal and wooden
b. fixed and portable
c. self-supporting and suspended scaffolds
d. assembled and delivarablr scaffolds
*it’s actually carpentry* two basic types of scaffolds are "self-supporting and suspended scaffolds." The correct option is c.
Self-supporting scaffolds are freestanding structures that do not require external support. They are commonly used in construction projects and are designed to provide stability and support to workers.
Suspended scaffolds, on the other hand, are suspended from an overhead structure or support system. They are typically used for tasks such as window cleaning or exterior building maintenance. They rely on ropes, cables, or other means to suspend the scaffold platform.
A. Metal and wooden: This option refers to the materials used to construct scaffolds. While metal and wooden scaffolds are indeed types of scaffolds, they do not categorize the scaffolds based on their structural characteristics or support mechanism.
B. Fixed and portable: This option categorizes scaffolds based on their mobility. Fixed scaffolds are permanently attached to a structure, while portable scaffolds are designed to be moved and set up at different locations. This categorization is based on the mobility aspect and does not provide information about the support mechanism or structural characteristics of the scaffolds.
C. Self-supporting and suspended scaffolds: This option correctly categorizes scaffolds based on their structural characteristics and support mechanism.
D. Assembled and deliverable scaffolds: This option does not provide a comprehensive categorization of scaffold types based on their characteristics. While scaffolds do need to be assembled, and some scaffolds may be delivered to the worksite, this categorization does not provide information about their support mechanism or structural characteristics.
Therefore, option c. self-supporting and suspended scaffolds is the correct option as it accurately classifies scaffolds based on their structural characteristics and support mechanism.

How can the motion of an object that is already moving change?
How can the motion of an object thatnis NOT moving change?
Answer:
"They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object"
"When a force acts on an object that is stationary or not moving, the force will cause the object to move, provided there are no other forces preventing that movement."
The answer to both questions is the same answer:
That can only happen if force acts on the object.
What is the general shape of the graph line?
A positively sloping diagonal
A negatively sloping diagonal
A half-parabola
A hyperbola
Answer:
A
Explanation:
Positive slope lines have a left to right ascent. A negative slope is present on lines that descend from left to right. Consequently, a diagonal line with a positive slope (/) would be to the right. Thus, option A is correct.
What is positively sloping diagonal?The height difference between two tile corners that is on the diagonal. A hidden value is used to determine if a tile can be seeded on, passed by a cart, or have the corner of the pavement tile lowered.
When two variables have a positive slope, it means that they are positively correlated; that is, when x rises, y rises as well, and when x falls, y falls as well.
A line on a line graph that has a positive slope rises as the line advances from left to right.
Be aware that a line's positive slope causes it to slope upward from left to right. Remember that a line with a negative slope descends from left to right. Keep in mind that a line has no slope when it is horizontal.
Therefore, positively sloping diagonal general shape of the graph line.
